BRAKE.

- Application filed October 10, 1923. Serial No. 667,633.

To all 'whom itmag/ cof/wem.' Y Y p Be it known thatwe, RAY L. SHUEY and ARTHUR C. MCGEE, `citizens of theUnited States, residing at Kansas City, Jackson County, Missouri, and Olathe, in the. county of Johnson and State of Kansas, have invented certain new and useful Improvements in Brakes; and we do declare the following to be a full, clear, and exact descripton of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to t-he figures of reference marked thereon, which form a part of this specification.

rl'his invention relates to vehicle brakes and the primary object thereof is to provide a simple form of brake 4especially adapted for use in connection with hand trucks. Means is provided whereby the brake may be automatically applied to wheels of the vehicle when the vehicle comes to a state of rest or when the tongue of the vehicle is lowered and the construction is such that the brake may be applied or released from either end of the vehicle, thus effecting a saving of time in handling the truck. i

The novel construction of Lthe invention will be apparent by reference to the follow- `ing description in connection with the accompanying drawings in which Fig. 1 is a vertical, longitudinal, sectional view through a truck to which my invention is applied. f

Fig. 2 is a cross sectionalrview through the truck on the line 2;'-2 of Fig'. v1. y

Fig. 3 is an enlargedfperspective View of the applicator showing its position to apply the brake. Y'

Fig. 4 is an elevational` view ofthe applicator showing its position to release the brake, and l Fig. -5 is a perspective view of the truck with the brake applied.

The truck may be of conventional' form and may consist of a platform or body 1 with bolsters 2 and 3 carrying the rear wheels 4 and 5 land the front wheels 6 and 0 T, the wheels 6 and .7 being secured to theY Y bolster 3 by a fifth wheel construction 8 and thetruck .be propelled'hy a tongue 9.

ll of the mechanism heretofore described conforms to known types of `trucks so our invention 1does not reside in the truck per se but rather in the construction of the brake mechanism whichvmay be associated`therewith.' v n A Depending from the platform 1 vis a bracket' 10 on which is pivotally secured a double thro-wAv lever 11 havingl two oppositely disposed arms 12 and 13 and a right an! gularly projecting arm 14. There is a con.- necting rod or link 15 pivoted to the' upper end of the arm 12 and -pivotally secured to an elbow lever 16 fastened to the bracket 17 at the front of the Vehicle. VThe elbow lever 16 has a forwardly extending arm 18 connected to the tongue 9 by, a flexible connecftion, for example a chain 19. The lower 'arm 13 carries a rearwardly extending rod form of the truck is a rock shaft 26 having' depending brake levers 27 and 28r carrying the brake shoes 29 and 30. The rock shaft carries a crank 31 to which is secured a ten `sion spring 32 Afastened to the bolster 2 so that there willbe anrinherent tendency 0f the spring to'a'pply the brakes. The arm 31 has secured tof-it a connecting rod 33 fastened to the double throw lever 11 at 34 above the pivot 35 which secures the throw lever ll'to the bracket 10. The forward end of the 'connecting rod 33 has a. bent` or olf set portion 36jso that when the `lever 11 is swung in one directio1i 4*the pivot 34 will be in line with the pivot 35 so that the brakes'will be held released but when the lever 11 is swungenough to allow the pivot 34 to move above the 'horizontal plane passing through the pivot 35, the spring can lexert its tension to apply the brakes. In Fig. 3 Ihave shown the lever 11 in position to per- .mit the brakes to be applied and in Fig. 4

tor may pushl up on the arm 23 ory raise the tongue ,91 and push up on the arm 18'so vas to throw the lever l1 about its pivot 35 in a cross wise direction exerting a pull on the connecting rod 33 toward the front of the vehicle and against the action of the spring 32 throwing the pivot 34 to the position shown in Fig. e' with the connecting rod resting on the top 37 provided to limit the swing movement of the lever ll, then the brakes will be released and the vehicle may be propelled. Then it is desired to apply the brakes the operator can drop the tongue 9 so that the chain or flexible `,connection 19 will exert. a downward pull on the arm 18 or he may exert adownward pressure on ,the arinv so as"y to throw the lever ll in a counter-clockwisey direction, raising the pivot slightly above a horizontal plane vpassing through .the pivot their the spring 32 may exert its tension to snap `.the brakes into braking position and of kcourse thjehrakes can again be released by'caus- .ing depression ofthe arml 18 or 23.

` ltwi'll be observed that the braking action and braking release movements of the braking `in echanisni may be Aaccomplished in a convenient and expeditious manner and t-liat thebrakes canbe conveniently applied'or released from either end of the vehicle.

`What we claim and desire v to secure by Letters-,Patent is:

l.' In combination lwitlia wheeled truck, a bracket, a pivoted lever on the bracket, a rock shaft, brakey levers on the rock shaft having brake A,shoes for engagement with ,the

- wheels ofthe truck, an afrni onl .the rock shaft, a spring connected lto a rigid part on the truck ,and to the arm normally urging the brakes' intoibrakng'position and aconnecting rod between the arm and the first named lever, the Aconnectiing; rod havingy -an 0E Set portion pvoted to' the first .named lever, the pivot being adapted to be swung 'below a horizontal plane passing through the .pivotal connection between the first nained lever and the lbracket when in one 'position tol oppose vthe spr-ing and adapted to be swung above a' horizontal planepassing ,through the pivotal connection between the first named lever and the bracket to perinit'the ,spring to function.
